Application filed August @1909. Serial No. 510,978.

To all whom it may concern:

Be it known that'I, FRED T. WILEY, of

1 Boston, in the county of Suiiolk and State tion whereby the pressure may be directed selectivelyfand successively to the several cylinders of an internal combustion motor comprising a plurality of cylinders.

Another object of the invention is to utilize the timer or distributer, as the case may be, of an ignition system. for directing the pressure of the fluid to the cylinders in j succession.

The invention is embodied in a plurality of conduits, one connected to each cylinder of the'motor, pressure, an independent valve in each conduit, an actuator, and means for coupling the valves successively to the actuator, said means and actuator including nets under the control of the ignition sys 'tem. The invention is adapted to be applied to an internal combustion motor having any number of cylinders,.and having an ignition system which may be cit-her a high tension system including a distributer, or a low tension system including a timer in the primary circuit. v i

For the purpose of illustration, the invent-ion is herewith shown in connection with an internal combustion motor comprising four cylinders and an ignition system of the low tension type, including a timer.

Of the accompanying illustrate one form in which the invention may be embodiedQ-Fignre 1 represents a diagram including a four-cylinder motor, a

, source of fluid under pressure, an electricspark-producing system, and electrically operated means controlled by the primary circuit for cont-rolling and directing the pressure of fluid to the motor cylinders. Fig. 2 represents an elevation, partly in section, of the valve mechanism and electrically operated means for actuating the valves. Fig. 3 represents a section on line-'3-3 of Fig. 2.

The supply pipe valve 16 whereby the supply to all of the y closed. Each branch or conduit 11, 12', 13, and 14 is provided with operative valve, respectively at 21, 22, .23, and 24. For the sake of convenience in operatiom'the four valves are arranged at equal distances from a common center.

Fig. 1 includes the primary circuit of an ignition system which is controlled by a timer 25.

connected to the timer bya conductor 27.

31, 32, 33, and 34 indicate respectively the primary windings of induction coils associated respectively with the cylinders 11, 12, 13, and 14; The primary windings are all connected to a common conductor 28 leading to the other side of the source 26 of current. The timer 25 may be rotated as usual by mechanism driven by the motor shaft so as to cause it to successively engage the stationary contacts 31, 32, 33 and 34'. These-contacts are here shown asconnected to binding posts 35 which are connected respectively to the primary windings by conductors, 41, 42, 43, and 44. The windings in the secondary circuits are indicated at 31 32, 33 and 34 and the respective spark gaps are indicated at 31*, 32 33* and 34. To those familiar with the operation of internal combustion motors, it is well known. that the circuits by which sparks are produced in' the cylinders are closed when the respectivepistons are at the compression ends of their strokes. The closing of each spark producing circuit by the timer 25 produces'a spark at the end of the compression stroke and before the beginning of the drivcylinders mav be.

By the coiiperation ofthe timer ,with the contacts 31', 32, 33 and 34, sparks current is caused to direct pressure of fluid successively to the several cylinders includes controlling electromagnets 51, 52, 53, and 54, one for each of the valves 21,22, 23, and 24. The electromagnets may be connected to the binding posts 35 by conductors 51, '52, 53

and 54. They are also connected to a common conductor 55, leading to a relatlvely large actuatingelectromagnet 56, hereinafte'r described. 'A conductor 57connects the magnet 56 with the return. conduct'cir 28 andmay include a switch 58. The switch here shown includes the handle 59 of the valve 16, and is arranged to close the circuit through the magnet 56' when-the valve is It will be observed that the magnet 56 is relatively large, whereas the magnets '51, 52,

53, and 54 are relativel'ysmall. .In consequence of the difit'erence'in size, the'smaller magnets are adapted to be more sensitive and to operate more readily than the larger magnet, and they are so a-rrarigedwith re,- lat-ion to the valves 21, 22, 23, and 24- that the larger magnet '56 may actuate said valves, and the magnets 51, 52, 53, and 54 moved against the tension-ofit's spring into .7

As shown by Figs. 2 and 3, the magnet 56 is 'of the solenoid type, andis provided with-a core or armature 45. The outeri'end of the. core car- ,ries a disk or plate 46 which-risadapted to be engaged by. latches 61, 62, 63, and 64"con-= nected respectively to the valves 21, 22, 23,

and 24. The latches are pivoted-at 65 to members 66 afiixed to thevalve stems 67, and they are connected to springs 68 by which they are normally retracted against adjustable stops 69.v

'71, 72, 73, and 74 indicate respectively armatures in cota'perative relation with the magnets '51, 52, 53, and 54. When either armature is attracted by its magnet, the latch carrying "the attracted armature is coiiperative relation with the disk 46, and when the diskis moved-bythe action of its ro riatejcf.v inder. the device is as follows :Assuming that the. motor in coming to a state "of rest stopsat" a pointlyvhich causes the timer 25 toengage .oneof the sta-- 'tionary contacts ihei cii'cuitis closedat that point throu ho'ne of the primary branches, and 'al'so,..t -ough one ofg'the. controlling;

magnets. When it is desired to start-the motor,.the handle 59 of the valve 16 may be turned to open the valve, and to also close the switch 58. The pressure of fluid in thereservoir 10 isthereupon admitted to'the 7o valves 21, 22, 23, and 24, and the circuit is closed throu h the appropriate controlling magnet, an also through the actuating magnet 56. The controlling magnet bein smaller and having a relatively light loa attracts its armature before the armature ofthe magnet 56 is moved. As the magnet 56 builds up, it finally becomes sufiiciently powerful toactuate 1ts armature which thereupon opens the valve which by that time is coupled with the plate 46. Pressure of fluid is thereupon admittedto the cylinder which 'is'the cylinder for otherwise driving the mo- .tor by an ignited charge of combustible gas. As the motor advances under the pressure of the fluid so delivered, the timer 25 is advanced to the next. succeeding contact, whereupon the next. succeeding. controllin valve isfirst coupled with and then actuate by the magnet 56 which is deen'ergized as often as the circuit is broken. A succession of driving impulses of the fluid from the reserv'oir 10 -may be permitted to drive the motor until the motor is'regularly driven by the combustion of the gas otherwise supplied to it. When the fluid from the reser- -voir'"10 is no longer required, the valve handle"59 is moved to close the valve and open the. switch 58, whereupon the motor may continue without receiving pressure I from the reservoir.
